This article examines Soviet housing policy in the annexed former Polish territories of Western Belorussia and Western Ukraine, which the ussr absorbed in September 1939. The author focuses on Western Belorussia and in particular on Bialystok, which was the largest and most economically developed city in the region. Bialystok and the Bialystok region contained the largest number of refugees, soviet soldiers, party clerks and technical specialists from the Soviet Union. This article looks at the area’s acute housing problem, which resulted in the theft of property and illegal eviction of apartment owners. The Jewish population of Western Belorussia found itself in the epicenter of events, since it was well represented among the refugees, particularly among the illegally evicted housing owners. The author analyzes the housing policy in Western Belorussia prior to the start of the German-Soviet War in 1941, the position of the Jewish population during this period, and the impact of the acute “housing problem” on the Sovietization of the local population.
